Specification of Letters Patent No. 1,806, dated October 8, 1840.

To all wh-0m t may concern Be it known that I, EDWARD L. YOUNG, ofNorfolk borough, in the county of Norfolk and State of Virginia, haveinvented new and useful Improvements in Twisting- Spindles; and I dohereby declare thatthe following is a full, clear, and exact descriptionof the construction and operation of the same, reference being had tothe annexed drawings, making a. part of this specification, in which-Figure 1 is a perspective View of the improvements made on the spindle.Fig. 2 is a longitudinal elevation of the same.

Description 0f the construction Cmd operation 07 my intention-Hy firstinvention consists in an improvement I have made on the fiier of thetwisting spindle: whereby the end-guide attached to it for receiving ordelivering the thread, is extended to such a distance from the sideguide, that abobbin can easily be put on, or removed from the axle ofthe spindle without disturbing the flier or end guide, which I thuseffect, after the cross head of the spindle has been strongly united tothe cylindric pipe of the customary spindle, viz: Near one end ofthesaid cross-head marked 6, Fig. 1, of the spindle I affix a wiresupporter marked 2, Fig. 1, say about one inch and three quarters inlength; and run the same parallel to the axis of the spindle; thedetached end of which wireI turn up in the form of the figure one,standing erect, and represented by No. L in Fig. 1, the turned upportion I term the side guide. I then take another piece of wire ofabout one foot in length;v

and at about one quarter of an inch from one of its extremities bendit-s end, so as to make an acute angle and represented by No. 3, inFig. 1. This portion I term the end guide. At about one quarter of aninch from the angular point of said guide inward I again bend the saidwire by giving it a curvilinear form, such as is customary in mostfliers and from said curve I straighten the residue of the said wire.The curve with the residue of the wire first stated I term a supporteror flier of the end guide. The straightened end of this flier, marked 15in Fig. 1, I strongly affix near to the unoccupied or remaining end ofthe aforesaid crosshead, marked 6 in Fig. 1, and when so doing I keepthe straightened or second part of the said end guide marked 3 in linewith the axis of the spindle, and at the same time place the inner partof said end guide at such an extended dist-ance from the crosshead ofthe spindle, that a. bobbin can be easily passed to or from the axlewire of the spindle without coming in contact with the fiier of the endguide.

New what I claim on this subject as my invention, and desire to secureby Letters Patent, is-

Extending the guide which receives or delivers the thread in aline withthe axis of the spindle sufliciently far beyond the end of the spindleto enable the operator to remove the bobbin without removing the flieras described.

I do not claim as my invention merely making the flier so that thebobbin can be removed from the axis of the spindle without removing ordisplacing the flier as this has long since been done for spinningcotton wool, &c., but in these cases the guides were of equal length andat equal distances fro the cross-liead of the spindle.

Now the guides being firmly affixed I next proceed to my method ofbracing the flier, and counteracting the centrifugal tendency of theimproved flier, when in active operation; which I effect by means of awire ring brace, which has its end or ends secured to the supporter ofthe side guide, which I thus effect. I take a piece of wire say aboutone foot in length and secure one end of about one inch and a half inlength to al side of the wire supporter of the side guide marked 2 inFig. 1, the detached portion I bent in the form of a circle or ringplacing its plane at right angles to the axis of the spindle, at thesame time making a part of the circle pass outside o-f, and preciselytouch the improved fiiers exterior surface marked 17 in Fig. 1. I thensecure the other end portion of the ring, to that portion of the ring,to that portion of the latter, it comes in contact with; or if moredesirable, turn this just stated portion in line with the nearest sideof the aforesaid side supporter marked l2 in Fig. 1, and firmly securethem together; by which method the flier of the end guide will be wellbraced to the supporter of the side guide, and its centrifugal tendencywill be efectlually overcome.

For this my method of counteracting the centrifugal tendency of theflier, at the same time bracing the fliers or supporters of the side andend guides, I claim as my invenpipe marked 16, aiiX a flanged rollelfora tion and desle to secure the same by Letband marked 7 in Figs. 1 and2. ters Patent.

Having accomplished thus far, I then ro- 5 ceed to the completion of thespindle by pss- EDXVARD L' YOUNG' ing through the cylinder pipe, marked16 in Wfitnesses: Fig. 1, an axle Wire for receiving a bobbin .T01-INTANIS, marked 14 in Fig. 1, also to the cylindric. JOHN VVHITEHURST.
